It must have been lost.

My workplace is an industrial facility, about 40 acres in size and roughly rectangular in shape. There are two plastic lined water retention ponds over on one side and a spray field, which is sort of naturalized, in one back corner.

I was returning from a site inspection walk on a not warm afternoon. It was about 8 degrees C or 46F and I was just outside the main admin building when something caught my eyes. I veered towards it.

A crayfish (I called them crawdads when I was in Texas) was at least 100 meters from the nearest pond, and more than 200 meters as the crawdad crawls from the spray field. About 4 inches nose to end of tail. It had no business being on the concrete pad behind the building. I can only speculate how it got there.

I seemed to remember they they burrow down into soft mud in cold weather. So I took it back to the edge of the water at the spray field where it had at least a chance.
